Which of the following are exterior angles?

B. ∠6, D. ∠2, E. ∠3, F. ∠4

Step-by-step explanation:

∠2, ∠3, ∠4 & ∠6 are exterior angles as they present outside the triangle. Here, only ∠1 & ∠5 are present in the interior of the triangle.

Hope it helps ⚜

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
